In an exclusive interview with PEOPLE magazine (which she also used to announce her cancer), Jen Arnold talked about her remission.

“I had my official last chemo treatment. And while I’m hesitant to say I’m cancer-free — maybe that’s common for people who have cancer — I’m doing great. Everything is moving in the right direction.”

It was determined that the 39-year-old suffered from stage 3 choriocarcinoma — a fast-growing “but often very curable cancer” that grows in the uterus, and starts in tissue that normally becomes the placenta — according to the National Institutes of Health.

Jen Arnold and her husband Bill Klein — who both suffer from dwarfism — star in TLC’s popular show The Little Couple, in which they share their daily lives and where Arnold, who is a neonatologist, shared her experience of going through chemo.

The reality TV star has two adopted children — three-year-old Will and two-year-old Zoey — and praised her husband for being her rock during her battle against cancer.

“Bill knows when I’m not doing well and he takes such good care of me. That was huge. That and enjoying watching my children play was a huge uplifting part of my treatment. With kids running around, you don’t have much time to feel sorry for yourself.”
